Use the PoE Port Settings page to enable PoE on the ports and monitor the current
power usage and maximum power limit per port.
This page limits the power per port in two ways depending on the power mode:
•
Port Limit—Power is limited to a specified wattage. For these settings to be
active, the switch must be in Port Limit mode. That mode is configured on the
PoE Properties page. When the power consumed on the port exceeds the
port limit, the port power is turned off.
•
Class Limit—Power is limited based on the class of the connected PD. For
these settings to be active, the switch must be in Class Limit mode. That
mode is configured on the PoE Properties page. When the power consumed
on the port exceeds the class limit, the port power is turned off.
To configure PoE port settings:
Click Port Management > PoE > Port Settings.
To edit the power limit per port, select a port and click Edit.
Enter the following information:
•
Interface—Select the port to be configured.
•
PoE Administrative Status—Enable or disable PoE on the port.
•
Power Priority Level—Select the port priority: low, high, or critical, for
power management when the switch power supply is insufficient. For
example, when the system power is not sufficient, and the PD is inserted into
port 1 which is prioritized as high, the power to ports with priority low may
be cut off for the power delivering of port 1.
•
Administrative Power Allocation—This field is displayed only if the power
mode is Port Limit. If the power mode is Power Limit, enter the maximum
amount of power in milliwatts allocated to the port. The range is 0 to 30,000
mW.
The following counters are displayed for each device:
•
Max Power Allocation—Displays the maximum amount of power in
milliwatts assigned to the PD connected to the selected port. In Class Limit
mode, the value of the maximum power allocation will be determined on the
class detection of PD connected, 15.4 w (802.3af, class 0 to 3), and 30 W
